Definitions

  • the invention relates to a support device between an element of large mass and a fixed support, making it possible to limit the displacements and accelerations of the element relative to the support, during movements caused by stresses such as those coming from an earthquake.
  • support devices which are intended to transmit forces between the supported element and the support which are constituted by anchors or joints.
  • devices have been devised associating two discs having concave surfaces with balls arranged between these two concave surfaces or pendular stirrups with spherical bearing, for supporting structures or machines in order to reduce the forces transmitted to the element carried from the media.
  • Anti-seismic support devices are also known which are used to protect constructions which comprise horizontal cylindrical rollers arranged in two superimposed assemblies, having perpendicular axes and interposed between support parts in which are curved and inclined rolling tracks ( US-A 761,660).
  • a relative displacement of the building with respect to the ground on which it rests is possible whatever the direction of the seismic stresses, this displacement being broken down into two displacements in two perpendicular directions.
  • These movements on the inclined tracks cause a vertical movement of the rollers and the building, which absorbs the energy communicated to the building by the earthquake and reduces the horizontal displacement of this building.
  • flanges at each of the ends of these parts corresponding to the axial ends of the roller.
  • Such a holding means does not however ensure the centering of the roller with respect to the corresponding bearing parts, since it is necessary to provide a certain clearance between the edges and the ends of the roller to allow its movements.
  • the roller can therefore move in the direction of its axis and rub and lock against one of the edges.
  • the roller can be placed at an angle with respect to the support parts, which results in faulty operation of the device.
  • the object of the invention is therefore to propose a support device arranged between an element of large mass and a fixed support, making it possible to limit the displacements and the accelerations of the element with respect to the support, during movements caused by stresses such as those from an earthquake, comprising cylindrical rollers arranged horizontally in two superimposed sets of at least two parallel rollers, the rollers of one set having their axes perpendicular to the axes of the rollers of the other set and one set of three support pieces completely independent of one another superimposed and having on their opposite faces rolling tracks inclined with respect to the horizontal plane and having a profile corresponding to the shape of the rollers in the longitudinal direction thereof, the rollers of the first assembly being disposed between the upper support piece carrying the element and the intermediate support piece and being in contact with the tracks facing the upper and intermediate support pieces and the rollers of the second set placed between the intermediate piece and the lower piece resting on a horizontal surface of the support, said rollers being in contact with the facing tracks provided on the lower and intermediate support pieces, device whose rollers are always perfectly centered with
  • each of the rollers comprises in the axial direction a central part of revolution and two end parts of revolution flared outwards.
  • the upper part of this support device is constituted by a support part 4, the upper part of which engages in part 3 of the support structure of the fuel element rack is produced in the form of a spindle vertical 6 comprising a shoulder 7 on which the structure 2 rests with the interposition of support pads 8.
  • This raceway 9 is machined on the lower surface of the part 4.
  • the support device also includes a second intermediate support piece 10 and a third support 11 itself resting on the bottom 12 of the reactor fuel pool.
  • rollers with horizontal axes 14 and 15 are arranged while between the support pieces 10 and 11 are also arranged two rollers with horizontal axes 17 and 18.
  • the axes of the rollers 14 and 15 parallel to each other are directed in a first horizontal direction X while the axes of the rollers 17 and 18 parallel also are directed in a second horizontal direction Y perpendicular to the direction X.
  • the support piece 10 has on its upper surface a raceway 20 and on its lower surface another raceway 21.
  • the support piece 11 has a rolling track 24 on its upper surface.
  • rollers 14 and 15 are in contact via the tracks 9 and 20 with the support pieces 4 and 10 respectively.
  • the rollers 17 and 18 are in contact with the parts 10 and 11 via the tracks 21 and 24 respectively.
  • the tracks 9 and 20 on the one hand, and 21 and 24 on the other hand, have a profiled shape in the transverse direction relative to the rollers and present in this direction a succession of ramps (such as 9a 9b and 9c on the way 9) having successively rising and falling profiles.
  • rollers 14, 15, 17 and 18 comprise a cylindrical central part and two conical short short end parts allowing the centering of these rollers relative to the rolling tracks which are also profiled in the longitudinal direction relative to the rollers to represent two parts inclined sides such as 9e and 9f for runway 9.
  • the roller 15 comprises a cylindrical central part 1 5a and two parts of conical ends 15b and 15c which come to bear respectively on the inclined surfaces 9e and 9f of the rolling track 9.
  • the rollers have on the other hand, axes of rotation (such as 25 for the roller 14) which make it possible to connect the rollers 14 and 15 on the one hand and 17 and 18 on the other hand, by means of a connecting piece such as 27 crossed by the end of the axis 26 of the roller 15 on which is screwed a nut 28 (or the assembly 26 ', 27', 28 'at the other end of the roller).
  • rollers 14 and 15 on the one hand and 17 and 18 on the other hand are thus connected to each other at constant center distance at each of their ends.
  • the three support pieces are then completely independent.
  • the horizontal translation can only occur with a vertical displacement of the upper part and therefore of the element carried.
  • the mass of the worn element is opposed by gravity to vertical displacement, which allows with a judicious choice of the shape of the raceway profiles to selectively combine the acceleration and displacement of the element relative to the support.
  • these lockers are made up of juxtaposed modular elements and each of these modular elements is supported on four devices such as that which has just been described.
  • rollers can be arranged at a fixed center distance thanks to a junction bar connecting their axes or, on the contrary, can be arranged freely individually or in partial groups, taking advantage of a special shape of the rolling tracks keeping the rollers in spaced positions. .
  • the rolling tracks can be attached to the support pieces or, on the contrary, machined directly in these support pieces.
  • rollers themselves can be made in one piece or on the contrary have several parts threaded on the same axis.
  • the device according to the invention can find a use outside the support of the racks for fuel assemblies in the storage pool of a pressurized water reactor.
